恢复变质岩石的原岩性质,是在变质岩地区从事地质填图、矿产普查和勘探工作时所面临的重要而又困难的工作。目前人们利用野外地质产状、变余结构构造、岩石化学、地球化学、同位素地质学,副矿物等多种方法和手段来探讨这一问题,其中的一些方法已被广泛利用,有些方法在国内已有介绍。本文以阜平群为例介绍苏联学都鲁金科(B. The restoration of the original rock properties of metamorphic rocks is an important and difficult task in carrying on geological mapping, mineral prospecting and exploration in the metamorphic rock area. At present, people use the methods of geological formation, structural alteration, petrochemistry, geochemistry, isotopic geology and side minerals to explore this problem. Some of these methods have been widely used, and some of them are widely used in China Already introduced. This article takes Fuping Group as an example to introduce the Soviet Union Xuedu Luke Branch (B.
